DOOR CALL Filed Nov. 20, 1931 INVENTOR.

ATTORNEY Patented Apr. 1933 EUGENE A. HOAG, OF PACIFIC GROVE, CALIFORNIAnoon can];

Application filed November 20, 1931. Serial 170. 576,405.

This invention relates to a door call and for the purpose of thisdisclosure is described and illustrated as a manually-operated,

mechanical Woodpecker, arranged to deliver a v 5 rapid succession ofloud taps on a resonator.

In the present instance my novel device is represented as being securedto the outer surface of a door, to act as a call. Obviously my inventionmay be applied to many other uses, such for instance as an ornamentaldesk buzzer to act as a call, or it may be used as a toy.

The structure of the bird-like body may be either of carved wood, wherea craft-manlike effect is desired for the more expensive devices, or itmay be molded from any suitable material such as papier-mach.

In the present instance the bird body is shown as a two-piece stampingcomprising a boat-like breast member adapted for attachment to a plate,and a back member which fits over the breast member like a cover,suitable locking-means being provided to hold said members together whenunited.

The objects of my invention comprise the following desiderata:

To provide a novel and attractive device resembling a Woodpecker, forattachment to a door or other resonant object and having means tosimulate the rapid tapping of a Woodpecker on a hollow tree.

To provide means to secure the bird structure to a relatively fixedstructure.

To provide a hollow body having internal mechanism adapted to vibrate abirds head against a plate or stud when operated by an external turnablelmob.

To provide a manually-operable knob at the right hand side of the birdsbody arranged to be twirled clock-wise by a users right hand whenstanding facing the device.

To provide a vibratory, curved stem extending forward in a beak-likemanner from a detent-controlled rock-shaft, and a birds head of suitablecementitious matter molded on the stem so that the end of the stem formsa hammer to beat against a plate or stud.

In the accompanying drawing,

Figure 1 is a side elevational view of my device attached to a verticalresonator.

Figure 2 is a front elevational view.

Figure 3 is a front elevational view of the vibratory mechanism. YF'gure 4 is a section taken on theline IV-IV of Figure 3, and throughthe head.

" Figure 5 is a section taken on the line V-V of Figure 1. 1

Figure 6 is a side elevational view of the member forming the birdsback.

Similar'reference indicia refer to similar parts throughout the severalviews.

In carrying out my invention I provide the concaved breast member 7secured to the resonator 5 by the screws or bolts 66.

The structure 7 is adapted to receive the clock-work unit C attached tothe interior 55 wall thereof by the lugs 9 and the screws 9'.

The unit 0 comprises the respective sideframe members 1O1O' spaced apartand secured'by the respective postsil, suitably nutted or riveted. Themain winding stem 13 extends outwardly through the lapped members of 7and 8 at 14, and carries the knob 15. a

The master gear 16 fast to the stem 13 meshes with the lantern pinion 17secured to the adjacent side of the escapement wheel 18 fast tothe shaft19 and nicely journalled in said frames. The detent20 rocks on the shaft21, also journaled in said frames.

The stem 22 carried by the shaft 21mounts the head 23 which may well bemoulded thereon and composed of any suitable cem entit-ious composition.

The coil spring 29 surrounds the shaft 21 and is adapted and arranged,normally and yieldingly, to hold the head 23 in the backward position,in which disposition the neck 24: overlaps the adjacent portions of thebody members 7 and 8 so as to exclude rain or 90 snow which may beatupon it.

It will be noted that the bounding edges of the member 7 are struckinwardly so as to leave the seat 26 for the companion edges A of themember 8 to abut against; the creases 27 being provided adjacent theedges of said member to inter-engage complemental creases forward on themember 7, thereby constituting locking means for binding said 7 memberstogether along the curved line 28 which simulates the rounded outer edgeof a folded wing.

When the knob 15 is twirled between finger and thumb in a clock-wisedirection the gear 16 acts on the lantern pinion 17 thus rotating theescapement pinion 18 thereby imparting rocking motion to the shaft 21through the detent 20, this in turn imparts a rapid vibratory motion tothe stem 23 causing the end of the beak 22' to sound a loud tattoo bystriking against the anvil 25.

I have shown the element C as a preferred means for producing theWoodpecker sound by my device but obviously other reciprocating meanscould be employed without departing-from thev spirit of theinvention,vor the scope of the appended claims.

I claim 1. In a device of the character described, a pair of shell-likebody members having overlapping meeting edges forming an inclosure, aframe supported within the inclosure, and carrying a springless geartrain including an escapement lever, a member associated with theescapementlever and movable. therewith, and a shaft extending throughthe overlapped edges at one side of the inclosure to retain the bodymembers. in assembled relation and providing a rotatable support for thedrive gear of the train.

2. In a device of the character described,

a hollow body member, a frame within the body member carrying spacedlugs for attachment to the body member, a springless gear trainsupported on the frame and including an escapement lever, a memberassociated with the escapement lever and movable therewith and a shaftjournalled in the frame and extendin through one side of the body memberand providing a rotatable support for the manually operated drive gearof the train and said body member carrying a base plate to facilitateattachment to a support.

,In testimony whereof I afiix my signature this 14th day of November,1931.

EUGENE A. HOAG.
